ColorCorrectOFX and similar plugins declare per-channel controls
(Gamma, Contrast, Saturation, Gain, Offset) as kOfxParamTypeRGBA.
Olive previously mapped every RGBA param to NodeValue::kColor and
rendered it as a ColorButton, which is semantically wrong for
adjustment sliders.
This commit adds heuristic semantic detection to distinguish
"true color" inputs (color pickers) from "per-channel scalar"
inputs (float sliders):
- label/hint/name keywords ("gamma", "contrast", "gain", ...)
- display range outside [0, 1]
- uniform default values across all channels
The detected semantic ("color" or "scalar") is stored as the
node input property "color_semantic". The display range and hint
are also persisted as "min" / "max" / "tooltip".
NodeParamViewWidgetBridge now branches on "color_semantic":
- "scalar" → 4× FloatSlider (reuses existing ProcessSlider /
keyframe-track logic, since kColor already splits into 4 tracks)
- otherwise → ColorButton (unchanged)
All 4 test suites pass.
Refactor FFmpeg frame processing and improve focus management in panels. Add memory sanitization for debug builds and update KDDockWidgets integration.
Simplify the frame reading process and metadata extraction in `ffmpegdecoder.cpp` by reducing redundant code and improving variable initialization. Add a helper function in `ffmpegdecoder.h` to map FFmpeg field orders to Olive interlacing types, enhancing code clarity. Adjust the condition for interleaved write in `ffmpegencoder.cpp` for better handling.
This commit extends the OFX plugin support in Olive by:
- Initializing and scanning for OFX plugins
- Updating PluginNode to handle OFX plugin parameters and inputs
- Adding necessary methods and properties for OFX plugin integration
- Enhancing NodeFactory to include OFX plugin nodes
- Refactoring and renaming OliveInstance to OlivePluginInstance
- Introducing new classes for parameter handling (ParamInstance)
- Adding PluginJob for rendering OFX plugins
- Adjusting CMakeLists.txt files to include new source files
This commit adds comprehensive support for OFX plugins in Olive, including:
- Add plugin node infrastructure with getPlugin() method
- Implement OliveHost for managing OFX plugin instances
- Create OliveInstance to handle plugin parameter and timeline interactions
- Add OliveClip implementation for plugin clip handling
- Implement region of definition (RoD) and region of interest (RoI) functionality
- Add interactive mode support in Current class
- Integrate plugin rendering into RenderProcessor
- Fix include dependencies and remove unused OlivePlugin.cpp reference
